Dynamic Redundancy Configuration for Availability and Resource Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing redundant technical systems incur unnecessary resource consumption and costs due to continuous operation of secondary systems, which often fail soon after taking over primary tasks, and fail to adapt to varying application requirements.
Innovation Solution
A computer-implemented method determines an optimal configuration for a technical system by evaluating predefined requirements and failure risks, considering sustainability criteria like resource consumption and carbon footprint, to dynamically select redundancy levels based on specific conditions.

Engineering Contradiction Analysis
1Reliability
If a redundant technical system with continuous operation of secondary system is used, then availability and reliability are increased, but resource consumption and operating costs increase
Solution Approach 1:
The patent implements dynamic configuration adjustment where the redundancy level of the technical system is not fixed but can be changed based on current operating conditions. The system evaluates multiple configurations and selects the optimal one by weighing availability requirements against resource consumption, allowing the secondary system to be activated or deactivated dynamically rather than operating continuously
Solution Approach 2:
The patent changes the parameter of redundancy level from a static state to a variable state. By evaluating different configurations with varying degrees of redundancy and selecting based on current needs, the system adjusts the redundancy parameter dynamically to match actual availability requirements while reducing unnecessary resource consumption
2Duration of action of stationary object
If additional redundant system components are used to counteract uniform wear, then service life is extended, but device complexity and costs increase
Solution Approach 1:
The patent performs preliminary evaluation of multiple configurations before selecting the optimal one. By assessing wear patterns, availability requirements, and resource constraints in advance, the system determines the appropriate redundancy level and configuration before implementation, avoiding unnecessary complexity while ensuring adequate service life extension
Solution Approach 2:
The patent applies partial redundancy rather than full redundancy in all scenarios. By evaluating whether complete redundancy is necessary or if partial redundancy suffices based on current operating conditions and wear patterns, the system achieves service life extension with reduced system complexity and lower costs
3Reliability
If redundant system is maintained during periods when not consistently required, then availability is ensured, but unnecessary costs and resource consumption arise
Solution Approach 1:
The patent implements periodic evaluation of configuration requirements where the system reassesses whether redundancy is needed at scheduled intervals or based on event triggers. This allows the system to maintain redundancy only during periods when it is actually required, switching to lower redundancy modes during periods when availability requirements are reduced, thereby eliminating unnecessary resource consumption
